Application filed April 2,

This invention relates to mattresses or cushions, and its principalobject is to provide a simple, durable and comparatively inexpensive sring construction for mattressesand cus ions which can be constructedand assembled with great rapidity and at considerably less cost than theordinary spring constructions for mattresses and cushions.

Another object is to minimize the amount of material employed in' theconnecting means between the coiled springs and thecovering material towhich the sprin s are attached. Another object is to provi e improvednon-metallic means whereby the end coils or convolutions of the springsmay be quickly and readily attached to the covering material for thesprings. Another object is to provide a plura 'ty of layers of fabricbetween the mlddle coils and end coils of the the minimum materialrequired the springs to the covering material, where b a more durablemattress or cushion is obtained.

With-these and other objects and advantages in view, this inventionconsists in the several novel features of construction, arment andcombination of parts hereina or fully set forth and claimed.

The invention is clearl illustrated in the drawing accompanyingwhichbetween the retainer strips and covering ma- Figure 1- is afragmental vertical cross section taken through a mattress or cushionspring construction, and illustrating a sim le embodiment of the presentinvention; 1g. 2 is a perspective view of a fragment of one of thecovers of thesp tion, and showing the spring retaining stripssecuredthereto; a

Referring to said drawin which illustrates a single embodiment o thepresent invention applied to a mattress or cushion, the

aracters 6, 6 designate two pieces of coverin material which enclose thesprings, an said pieces may be of the desired size and shape to form aspring conreference c or connecting stitches are spaced a t isspecification in P 'open corners into w 'the springs are inserted, andthe four closed construe- 1928.

preferred to use coiled springs of that type in which the end coils areof a greater diameter than the intermediate ones, such a t pe of springbeing I strips 0 fabric material ,8 are stitched to the inner sides ofthe covering material 6 by rows of stitches 9 that run transversely ofthe'strips through which they pass and run parallel with andapproximately midway between the other strips.

There are two layers of strips, the strips of one layer extendingparallel with each other and running in one direction, and the strips ofthe other layer'extending parallel with each other and running in adirection at right angles tioned layer. spaced apart The strips of eachla or are (center to center) a istance to the strips of the firstmenshown in the drawing. he

en coils of the springs, and the rows of art a distance a proximatelyequal to or s ightly greater t an the diameter of the end coils of thesprings.

The covering material and arts of the strips bounded by the adjacentrows of stitches, form square pockets havin hich the end coils 10 0portions of the sides of said pockets confine the end coils ofthesprings against displacement with respect to the covering materialand locate the springs in proper position relative to each other throbout the extent of the spring construction. attaching the coiled springsto end coil of a sprin is inserted between two intersecting parts 0 thestrips and the covering material and turned upon its axis until thewhole or-greater part of-the end coil is brou ht between the strips andcovering materia Both ends of the springs are attached to the coveringmaterial in the same manner,

intersecting the covering material,'the Q after which the sides andendsof the spring construction are closed in the usual manner and theusual cotton, felt, or the like, laced around it and covered with theusual outer tion pertains.

It is apparent that a much simpler, neater and more efiicient springconstruction is obtained with the use of the intersecting strips ofmaterial attached to the covering material as described, than anyconstruction where layers of stitched together material are used inwhich slits are formed in one of the layers through which the end coilsof the sprmgs are inserted.

Furthermore, the intersectin portions of the strips provide two layers 0material between the midille coils and end coils of the springs, therebygreatly increasing the efficiency of the mattress or cushion. When thespring is compressed, in use, the middle coils are pressed against theintersecting coils of the coiled springs is facilitated, be-

strips, and because of the double thickness of material between themiddle coils and end coils, the life of the mattress or cushion islengthened. This is particularly noticeable. .in mattress or cushionshaving springs of which the diameter of the coils decreases toward themiddle of the spring. The intersectin provi es three layers which fullyrcsistthe tendency for the springs to push through the material.Furthermore, since the strips are whole throughout their extent, thetendency to fray out at slit places is eliminated, and, conse uently,they last longer than a slit layer 0 material. 1

Furthermore, the machinery for making the slits, and the time and laborrequired in making them is eliminated, and, consequently, the cost ofproduction is reduced considerably. Furthermore, a-saving is bad:

because the strips may be formed of material that would otherwise. bewaste material. Also, by reason of the open corner construction of thepockets, the insertion of the end cause the workman is able to observethe end coil as it is turned around in the pocket.

More or less variation of the exact details of construction is possiblewithout departing from the spirit of this invention. I desire,therefore, not to limit myself to the exact-form of the constructionshown and described, but intend, in the following claims, to point outall of the invention disclosed herein.

I claim as new, and desire to Letters Patent:

In a spring-construction, the combination of a fabric covering,intersecting fabric strips lying in planes substantially parallel withand secured to said fabric covering by rows of fastening means runningcrosswise through each strip at places between the intersections of thestrips, whereby open cornered pockets are formed and coiled springshaving open-ended coils confined in the pockets between intersectingstrips and the fabric covering with the ma'or portion of said end coilscovered by said intersecting secure by strips, together with thecovering,

tion of a fabric covering, intersecting fabric strips lying in planessubstantially parallel with and stitched to said fabric covering by rowsof stitches running crosswise through each strip at places between theintersections of the strips, whereby open cornered pockets are formedbetween the intersecting strips andcovering material, and coiledsprings, having open end coils which are insertable into the pocketsthrough the open corners thereof and confined therein with the majorportion of said end coils covered by said intersecting strips, theextent of said corner openings being less than that of the end coils,whereby displacement of the end coils through the corner openings isprevented.

5. In a spring construction, the combination of two spaced fabriccoverings, each having intersecting fabric strips lying in planessubstantially parallel therewith on the face opposed to the othercovering, said strips being stitched to their associated covering bystitches running approximately midway beciated covering with the majorportion of tween the perallel strips and through the said end coilscovered by said intersecting strips which lntersect them and therebyform strips, the extent of said corner openings 10 open corneredpockets, and coiled springs exbeing less than that of the end coils,whereby 5 tending between said coverings and having displacement of theend coils through the their end coils held in the pockets between thecorner openings is prevented.
